Firstly, the Four Noble Truths are not the first four Seven Truths. They are different.
These are the Seven Truths:
1. Knowledge of the pains and miseries of this world
2. Knowledge of human fragility
3. Knowledge of desire and sin
4. Knowledge of the human mind
5. The Tree of Knowledge
6. Human consciousness
7. The Tree of Life
The Seven Truths are taught one per root race. We are in the fifth root race, so we have been learning the fifth truth. The fourth truth was taught in the Atlantean era, and so on back in time.
The Four Noble Truths were taught by Buddha Shakyamuni in the Piscean era of the fifth root race, so it was the preamble to the unveiling of the fifth truth.
The fourth truth you quoted above is in reference to the Four Noble Truths.
The fifth truth you quoted above is from the Seven Truths.
